High-order harmonics from backscattering of delocalized electrons
It is shown that electron backscattering can enhance high-order-harmonic generation in periodic systems with broken translational symmetry. Paradigmatically, we derive for a finite chain of atoms the harmonic cutoff due to electrons backscattered from the edges of the chain and demonstrate a maximum...
